HTH Shock Treatment for Pools, 5.5 Pounds, Fast-Acting Pool Chemical

Quickly eliminate unwanted bacteria and algae in your indoor and outdoor swimming pool with HTH Shock Treatment. The convenient and easy-to-use product gives your pool a boost of chlorine for crystal clear water within 24 hours. The fast-acting multi-purpose shock product kills bacteria and algae, restores crystal clarity to pool water within 24 hours, reduces chlorine odor and eye irritation caused by swimming pool water, and won't fade liners. It is convenient, easy to use and won't over stabilize your pool.

TO USE: Make sure your pH level is between 7.2 and 7.8 and adjust if needed. Check that your pump is running and then snip the corner of the shock product. Broadcast over a wide area in the deepest part of your pool. If the granules settle at the bottom, use a brush to disperse them. When your free available chlorine levels are between 1 and 4 ppm, your pool is ready for action.
